UNIX / Linux信号处理：SIGEV_THREAD(UNIX/Linux signal handling: SIGEV_THREAD)

 我在代码中放置了一个简单的信号处理程序。 我已经初始化sigevent结构，并使用处理函数来捕捉信号。 
 
 有人可以指出为什么代码不工作？ 理想情况下，如果有信号，我的处理程序应该被调用。 但事实并非如此。 
 
 请帮助我，谢谢Kingsmasher1 
 
enter code here
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
#include <signal.h>
#include <time.h>

void my_handler(int sival_int, void* sival_ptr)
{
 printf("my_handler caught\n");
 signal(sig,my_handler);
}

int main()
{
 struct sigevent sevp;

 sevp.sigev_notify=SIGEV_THREAD;
 sevp.sigev_signo=SIGRTMIN;
 sevp.sigev_value.sival_ptr=NULL;
 sevp.sigev_notify_function=(void*)my_handler;
 kill(0,SIGRTMIN); // This should invoke the signal and call the function
}

I have put a simple signal handler in my code. I have initialised the sigevent structure, with a handler function to catch the signal.
 
Can someone please pin-point as to why the code is not working? Ideally if there is a signal, my handler should be called. But it is not.
 
Please help me, Thanks Kingsmasher1
